When turning it with the starter, you probably won't be able to hear the faint clicking of the injectors. =20 =20 If you want to test the operation of an injector (to see if it's stuck), just unplug the connector, put 12V on one terminal of the injector, and touch a grounded wire to the other terminal.

I'll just finished welding my exhaust system, which was the = last major fabrication job, so it's nothing but hoses and wiring to make it = run again.
